"vetrans pls help" is really a bad topic title to grab immediate attention of everyone.
Please do not create duplicate threads for same query, have merged both for now.
You can bump your original thread if none has replied.

To my knowledge no commercial paints now available in market will be able to sustain inside the water painted on thermocole. It will either fade or peeled off. Also slime and dirt will dim the colours. It may also affect the water quality. May be you have to use paints used for painting exterior of the ships. But will that also can be painted on thermocole, I have no idea.
If such a good paint available let us all know.
